The electroreduction of Co(II) and Co(II)+Mn(II) in air and water stable 1-butyl-3-methylimidazolium trifluoromethanesulfonate (BMIMTfO) ionic liquid was studied using cyclic voltammetry at 363 K. Reduction of Co(II) ions to Co is possible in the ionic liquid. Mn(II) cannot be reduced alone, but Co-Mn can be codeposited from the ionic liquid. Electrodeposition of Co-Mn coatings were investigated at various cathodic potentials (-1.2 to -1.5 V) in BMIMTfO containing CoCl2 (0.20 mol L-1) and Mn(TfO)2 (0.10 mol L-1) using constant potential electrolysis experiments on copper. The electrodeposits were characterized using scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), and X-ray diffraction (XRD) techniques. The Mn content in the Co-Mn alloy coatings varies from 9.86 to 29.6 wt% with the applied cathodic potential.
